I have a search form with a number of text boxes only one of which has to be filled in. If none of the boxes are filled in and you post the form you will always get is_valid($_POST) = true because the submit button will have a value. How do you handle the case where none of the variables are filled in and you want to generate an error message like "You must complete at least one of the fields."
